To all whom it mag concern! Be it known that we, JEAN LEON MULLER andJonas RoUss T, citizens of the Republic of France, the former residing,at Sannois o making kinematographic glass plates according to ourapplication, Serial No. 419,311, filed March 5, 1908.. The apparatus mayalso be used as a projecting apparatus for use with such kinematogra hicplates after they have been made, an also as a device to directly takeon one glass plate a number of views of animate objects.

With I these ends in view the invention consists in the novel featuresof construction and combinations of parts to be hereinafter describedand claimed.

In the accompanying drawing, Figure l is a rear-elevation, with partsremoved, of the apparatus, Fig. 2 is a vertical section on line 2, 2,Fig. l, and Fig. 3 is a horizontal section on line 3, 3, Fig. 1.

The apparatus comprises a casing A in which a lass late a is so movedthat a number 0 small views may be photographically reproduced, side byside, over the entire surface-of the plate, in connection with alight-opening B in the casing in which is mounted an objective u. Theplate a is fixed in a frame I) capable of vertical displacement inslides 0, which form art-of an assemblage which is itself capable ofdisplacement on the fixed'horizontal slides d. These displacements areregulated in such a manner that the different views of the lowerhorizontal row'of the plate first of all pass in succession in front ofthe objective, the plate moving in the direction indicated by the arrow1; .at the extremity of this row the plate is depressed by the height ofa view; the plate 1s then again displaced horizontally, but' in theopposite direction to the arrow 1, and all the views in the secondhorizontal rows pass in succession in front of the objective; at theextremity of this row the plate is again depressed and the third row ofviews is level with the obect ve. In this manner the plate is subjected'to'a reciprocating horizontal movement regularly interrupted at the endof each travel by a depression corresponding to the height of a view.The movement is produced by a handlee driving a toothed pinion f whichmeshes with a gear-wheel g..

The gear-wheel -g carries on one of its faces, in proximity'to itsperiphery, a series of ribs, the uniform arrangement of which serves toproduce sinuous paths 7:. in which pins 12 engage; these pins correspond1n .number to the views in a horizontal row a manner that a completerotation of this wheel produces a displacement of the bar 7' andconsequently of the plate a, first in the direction indicated by thearrow 1 and then in the opposite direction. The bar 7' is guided in itsdisplacements by the rollers k.

In addition to the ribs indicated, the wheel 9 is provided (at one onlyof the places at which the direction of the paths h changes) with a bossI acting at each semi-revolution of the said wheel, alternately uponeach of the rollers m and, 11. solid with the whole constituted bythevertical slideways c, the bar 7' and a device located behind theplate-holding frame I) and which, as will hereinafter appear, serves tosu'pport the latter. arrangement comprises aplate 0 carried by the partof the system which is movable in the horizontal direction; this plateis slotted at p and q in such a manner as to form slots.

in whichla, certain number of pins 1', 'fixed on the uprights orvertical parts of the frame I), are able to en'ga e. Stops s are formedin the slots 7), g-{an 'the pins 1' enter these stops after eachvertical displacement of the plate. The vertical intervalbetween' Thisthe handle 6 be turned in the direction indicated by the arrow 3, thegear-wheel is driven in the direction indicated by the,

arrow 4. The first .pin 71 of the bar traverses the sinuous peripheralpath or groove h in which it is engaged; in doing so it reaches h wherethe path formsan incline;

the wheel g continuing to' rotate, as will be understood; a tractiveeffort is produced upon the bar j and the part of the system which ishorizontally displaceable moves in such a manner that the second view ofthe first horizontal row moves in front of the objective. At the sametime the second pin ?I ,of the bar j has entered the following sinuouspath; a displacement similar tothe preceding one is produced. Allthe'pins i come in succession in a path it; when the last pin isthusengaged-the plate has reached the limit of its travel in thedirection indicated by'the arrow 1 and the wheel 9 has made asemi-revolution.

been displaced simultaneously with the plate. The effect of thisencounter is the; displacement of the plate 0 relatively to the tion tothat indicated by the arrow 1 and the second horizontal row of the viewspresent themselves successively in front of the objective also in thedirection opposite to that indicated by the arrow 1. When the wheel 9has effected a complete revolution, the boss Z encounters the roller mand the plate is again. depressed. The operation is the same until allthe views have passed in front of the objective in the order set forth.The shaft t which carries the gear-wheel g is hollow. When the apparatusis used for photographing on a reduced scale the images from a band offilm, the tubular shaft 25 is'provided in front with a perforateddiaphragm plug .2. The luminous rays then pass through the objective atand fall on the plate where theirv area is'limited by theiwindow uformed :at the extremity of the cone. c. 'When the apparatus-serves forprojection, the plug a is. unscrewed and the rays of anappropriatesource of light pass through the tubular shaft, the plate,

I the Window and the projection objective in the opposite direction. Theshutter 11 with four screens 4: is actuated by the toothed pinion aswhich meshes with another pinion y keyed upon the shaft 25 of thegear-wheel g. Thus it is automatically operated by the At this moment.the boss Z encounters the roller 0?. which hasv teases plate-movingmechanism. Finally it should be noted that the special apparatus whichhas just been described may be utilized, without modification, forphotographing animate objects directly whenever the magnitude of theprojection does not exceed the limit'at which the grain of the platewould be visible. in this case the apparatus is arranged in alight-proof asing and a very rapid special plate is replaced bya'sensitized plate.
